Generally, in this coal liquefaction method, a slurry containing a mixture of pulverized coal, a solvent such as a hydrocarbon having a boiling point of about 150°C or more, and various catalysts is preheated through a preheater, and if necessary, the preheating is Before and after (preferably before) hydrogen gas or a reducing gas containing or generating hydrogen (for example, Co+H2O, Co+H2O+H2, Co+H
The preheated slurry and the high-pressure reducing gas are subjected to a liquefaction reaction in the presence of a catalyst in a reactor. However, depending on the type of raw coal, catalyst components contained in the coal may be used without adding a catalyst for this liquefaction reaction, but in general, a separate catalyst is used to liquefy the coal. It increases the efficiency of the reaction.
